Kaspersky no longer installing on 12.3 using pkg

[TobiasO]

Hi folks,

I am looking to see if anyone can help me with this issue.

We have been deploying the Kaspersky agent, and a separate PKG file for the Endpoint Security. 

After 12.3 this suddenly stopped working. When opening the Kaspersky DMG, and going through the setup, it works fine.

But when opening the PKG files, it fails in the end. This broke after 12.3

Would anyone have any advice where to start to get this working again?

Additionally: 
The Deployment through the Kaspersky Server never worked for us at MacOS, gets stuck at 51% that's why we are using the PKG file.
